MACARONI-DRIER.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed November 3, 1917. Serial No. 200,038.

To all whom it may concern:

Be it known that we, JOHN V. CAnErA, a citizen of the United States, andPRIMIANO CASALENA, a subject of the King of Italy, both residing atChicago, in the county'of Cook and State of Illinois, have inventedcertain new and. useful Improvements in Macaroni-Driers, of which thefollowing is a specification.

This invention relates to a macaroni drier and has for its object theprovision of an apparatus for circulating air through and about-asuitable. chamber in which macaroni is disposed for the purpose ofremoving the surplus moisture.

A further object of our invention is the provision of an apparatus ofthe character described which may be easily regulated to produce uniformdrying regardless of the exterior atmospheric conditions.

A still "further ob ect of our invention is the provision of anapparatus through which,

the air flows with a minimum of resistance so that a fan of relativelylow capacity requiring a small amount of power may be Another object ofprovision of an apparatus which is readily accessible so that the dryingchamber may be quickly filled and discharged from time to time.

Further objects and. advantages of our invention reside in the variouscombinations as hereinafter described as will be better understood byreference to the following specification when read in connection withthe accompanying drawing illustrating the preferred embodiment thereof,in which- Figure l is a longitudinal section through a drier accordingto our invention;

Fig. 2 is a transverse section through the drier;

Fig. 3 is a detail in elevation of one of the drying racks, and v Fig. 4is a fragmentary detail in perspective illustrating the structure of thedrying racks; v

Our improved drier comprises an outer shell having side walls 5, endwalls 6 and a top 7. The walls are preferably double, as indicated inFigs. 1 and 2, inclosing air spaces which insulate the interior of thedrier and prevent temperature changes bherein corresponding to changes11]. the sur5 our invention is thev of the drier above the dryingrounding atmosphere. Doors 8 and 9 in one of the side walls 5 adjacentthe ends of the drier give access to the interior thereof. These doorsmay be otherwise disposed but are conveniently arranged as shown in thedrawing. a

Within the outer shell above described we provide transverse partitions10 and 11 extending across the chamber. These partitions consist of aplurality of shutters connected to louvers 12 and 13 which permitmanipulation of the shutters to adjust the opening therebetween. Aceiling '14 extends across the chamber connecting upper edges of thepartitions 10 and 11" and forming therewith an inner drying compartmentto which access is obtained through doors 15.

afan 17 ing 21 to permit regulation of the passage f of airtherethrough.

Steam pipes 23 are arranged-transversely;

compartment on either side of the fan 17. The top 7 of the drier ispreferably in Fig. 1 in order that passage of air may be minimized. Thusa motor of relatively small capacity is sufficient to maintaincirculation of air in the apparatus. Inlet openings 24. are provided inthe end walls 6 of thedrier and are controlled by suitable doors'27which are preferably arranged in three separate sections as curved asindicated the resistance to the indicated in Fig. 2 to permit air to bedirected to different portions of compartment. v

The macaroni is supported in racks 28, Fig. 3 mounted on casters 29, theracks 28 preferably constructed of angle lIOIlSO-COII- the drying.-

nected by cross bars 31'having recesses 32 therein to receiveround bars33 which are removably mounted in the. recesses and over which themacaroni is hung as soon as it is received from the press. The racks 28are than wheeled into the drying compartment through the doors 15 whichare'closed, after which the drying OPbidElOIl is continued withoutdisturbing the racks by suitable regulation of the damper 22 and doors27. The shutters in the partitions 10 and 11 may also be adjusted tocontrol the flow of air which is caused by the rotation'of the fan 17.The speed of rotation of the fan may be adjusted at will by suitableregulating devices (not shown) for controlling the motor. When thedamper 22 and doors 27 are closed, the air within the drier circulatesthrough and about the drying compartment and is heated by the steampipes 23. When the damper 22 and doors 27 are open the air is drawnbetween the shutters through the macaroni in the racks and is exhaustedthrough the outlet opening 21.

From the foregoing description it will be apparent that we haveperfected an apparatus embodying numerous novel features of constructionwhich facilitate the handling and drying of macaroni which has beenheretofore largely dried in trays. These trays are very bulky andrequire considerable handling as well as careful arrangement of themacaroni therein prior to the drying operation. Our invention makes itpossible to materially shorten the time required for properly dryingmacaroni without producing a product in any way inferior to goods driedin apparatus heretofore in use. The air in my apparatus is so evenlydistributed that the macaroni dries uniformly throughout the dryingcompartment and it is unnecessary therefore to shift the racks duringthe drying operation. Thus one of the inherent disadvantages of dryingapparatus having forced circulation and usually provided with a fan atone end of the drying compartment, has been overcome in my apparatusthrough arrangement of the fan in the top of the drying compartment sothat it draws the air from both ends thereof.

Various changes may be made in the form, construction and arrangement ofthe parts without departing from the spirit and scope of the inventionor sacrificing any of its material advantages, the form hereinbeforedescribed being merely the preferred embodiment thereof.
